Street Light With Heat Dissipating Device

Abstract

A street light includes a post with a light unit connected thereto. The light unit defines an enclosed space therein, and a separation board located in the enclosed space to divide the enclosed space into a first space and a second space. The separation board includes a hole. A circuit board includes multiple light emitting members and is located in the first space and on the separation board. The light emitting members are received in the hole of the separation board. A heat dissipating device is located in the first space and secured on the circuit board. The heat dissipating device extends to outside of the light unit. The heat generated from the light emitting members is transferred to the heat dissipating device which transfers the heat to outside of the street light.

1 . A street light, comprising
 a post;   a light unit connected to the post and including a top cover and a lower cover which are connected together to define an enclosed space, a separation board located in the enclosed space to define a first space and a second space, in which the first space is located between the top cover and the separation board and the second space is located between the separation board and the lower cover, the separation board including a hole;   a circuit board including a plurality of light emitting members and located in the first space and secured on the separation board, the light emitting members received in the hole of the separation board;   a heat dissipating device located in the first space and on the circuit board, the heat dissipating member extending to outside of the light unit; and   a positioning device positioning the heat dissipating device to the circuit board.   
   
   
       2 . The street light as claimed in  claim 1 , wherein the heat dissipating device is a heat pipe. 
   
   
       3 . The street light as claimed in  claim 1 , wherein the light emitting members are Light Emitting Diodes. 
   
   
       4 . The street light as claimed in  claim 2 , wherein the heat pipe extends along the post and at least one mounting member secures the heat pipe on the post. 
   
   
       5 . The street light as claimed in  claim 2 , wherein the heat pipe includes a plurality of fins connected thereto. 
   
   
       6 . The street light as claimed in  claim 5 , wherein the heat pipe extends along the post and at least one mounting member secures the heat pipe on the post. 
   
   
       7 . The street light as claimed in  claim 4 , wherein the heat pipe is connected to an outside or an inside of the post. 
   
   
       8 . The street light as claimed in  claim 6 , wherein the heat pipe is connected to an outside or an inside of the post. 
   
   
       9 . The street light as claimed in  claim 4 , wherein the heat pipe is a single one or multiple ones. 
   
   
       10 . The street light as claimed in  claim 6 , wherein the heat pipe is a single one or multiple ones.
